Improved structure of switching connecting rod of industrial sewing machine

Abstract

The invention discloses an improved structure of a switching connecting rod of an industrial sewing machine. The industrial sewing machine is fixed in an inverted L shape on a horizontal working table top below the industrial sewing machine, the switching connecting rod structure comprises a connecting rod body, an eccentric pin, a backstitch adjusting assembly and a feeding adjusting assembly, on a right-side projection drawing of a vertical section of a machine head, an operation panel box body is embedded inside the middle portion of a casing on the left side of the switching connecting rod structure, the switching connecting rod structure is arranged on the lower right side of the operation panel box body, the connecting rod body is in an reversed S shape, the upper end of the connecting rod body is transversely folded over leftwards to form a backstitch hook, the backstitch adjusting assembly is arranged on the left side of the connecting rod body, the lower end of the connecting rod body extends downwards vertically, a connecting bolt is installed on the extension section, the lower end of the connecting rod body is then bent in an oblique direction towards the lower left side and is finally bent vertically, and the feeding adjusting assembly is located below the backstitch adjusting assembly. According to the improved structure, the structure of the switching connecting rod is improved, a control panel is integrated on the machine head, products can be packaged and sold conveniently in an all-in-one machine mode, a user can use the structure conveniently, the package and the transportation are conveniently, ad the package cost and the transportation cost are greatly reduced.

Description

technical field [0001] The invention relates to the field of industrial sewing machines, in particular to a switching link structure of an industrial sewing machine. Background technique [0002] With the development of mechatronics in industrial sewing machines, modern industrial sewing machines generally integrate operation panels, mechanical components, servo motors, and electronic control components. However, most of the current industrial sewing machine operation panels are external, placed on the top of the machine head and fixed with screws. During transportation and packaging, in order to avoid the heavy machine head from crushing the operation panel, the two should be packaged separately and placed, causing the transportation package to be damaged. The cost remains high, and the split structure causes many integral parts of the sewing machine, which makes it inconvenient for the user to assemble after purchasing. [0003] The head of the industrial sewing machine i...

However, most of the current industrial sewing machine operation panels are external, placed on the top of the machine head and fixed with screws. During transportation and packaging, in order to avoid the heavy machine head from crushing the operation panel, the two should be packaged separately and placed, causing the transportation package to be damaged. The cost remains high, and this split structure results in many overall parts of the sewing machine, which makes it inconvenient for users to assemble after purchase

[0003] The head of the industrial sewing machine is in an inverted "L" shape, and is fixed on the horizontal workbench below it through the vertical section on the right side. The inside of the head is a cavity, and various moving parts are compactly arranged in the cavity, so , if the operation panel is to be integrated on the machine head, the operation box behind the operation panel must be embedded in the machine head, which will inevitably interfere with the internal structure of the machine head
